That question matters, but it misses the more dangerous failure mode. A test can return to green after an AI repair while checking the wrong element or the wrong behavior. This Q&A examines that “false-heal” problem, the benchmark evidence behind it, and practical safeguards for teams using AI in their quality pipelines. **What is a “false heal” in AI-assisted test automation?** A false heal occurs when an AI-based test repair system changes a locator or interaction so the test runs successfully, but the test no longer checks the intended user behavior. The pipeline is green, yet the assertion has effectively been weakened or redirected. That is different from an ordinary failed repair: the dangerous case is the repair that looks successful while losing its original meaning. **Why is this problem easy to miss?** Most tools emphasize healing success: whether a broken test can be made to execute again. That is a useful operational metric, but it does not answer the more important question—did the repaired test preserve the original oracle? A test can pass because it found the wrong element, clicked a different control, or stopped exercising the behavior that mattered. Without an independent check, the green result can be misleading. **What did your benchmark examine?** My benchmark evaluated self-healing behavior across 136 controlled UI perturbations, two applications, and four resolver approaches. The design paired the repaired test result with an independent assessment of whether the intended target and behavior were preserved. The purpose was not to produce a universal vendor ranking; it was to make a failure mode measurable and reproducible. **What did you observe?** In the benchmark, unsupervised healing resolved the wrong element roughly one time in four under the tested conditions. That figure is a benchmark result, not a claim that every tool or production workload will have the same rate. The broader finding is that false heals are common enough to deserve their own measurement rather than being treated as an edge case. **How should teams interpret vendor healing-success numbers?** Treat them as repairability numbers, not as proof that the test still validates the intended behavior. Teams should ask what counts as success, whether the original semantic target is checked independently, what workloads were included, and how often repairs are reviewed by a person. A high healing-success rate can coexist with an unacceptable false-heal rate. **What should engineering teams measure instead?** At minimum, track repair success, false-heal rate, test-oracle preservation, review rate, and the time between an automated repair and human approval. The exact definitions should be documented before comparing tools. If a team cannot tell whether a repaired test still targets the same behavior, it is measuring execution continuity rather than test validity. **Does this mean teams should stop using AI test repair?** No. AI repair can reduce maintenance work and help teams recover from routine UI changes. The answer is to put a verification boundary around it. High-risk tests should require semantic checks or human review, and automated repairs should be observable, reversible, and linked to the change that triggered them. The goal is controlled assistance, not blind autonomy. **What is a practical first step a team can take next week?** Choose a small, representative set of tests and manually label whether a repaired locator preserves the intended target. Run the same set through the current repair workflow, record both green execution and semantic correctness, and calculate the false-heal rate. That gives the team a baseline and quickly reveals whether its current “success” metric is too narrow. **What is the larger lesson for AI in software quality?** AI systems need failure metrics that reflect meaning, not just activity. A job that ran is not necessarily a job that did the right thing; a test that passed is not necessarily a test that checked the right behavior. The engineering discipline is to make uncertainty visible and to refuse to convert an unverified repair into a green signal. **Where can readers learn more?** The benchmark and supporting material are available at https://github.com/SuneetMalhotra/visual-oracle-bench.
